A New Species of Pararrhopalites Bonet & Tellez (Collembola, Symphypleona, Sminthuridae) from Iron Caves in Brazil.

A second species of the genus Pararrhopalites is described from caves inserted in iron ore lithology. Both species present a particular sensory organ in the interantennal region. The new species, Pararrhopalites ubiquum n.sp., has a wider distribution and it is not restricted to a single cave, as it is the case of Pararrhopalites sideroicus Zeppelini & Brito, in Fla Entomol 97(4):1733-1744, 2014, being found even in the Mesovoid Shallow Substratum. An update to the previously published identification key is presented.
